To all 'whom z't may concern:

Be it known that we, ARTHUR J. PETERSON and Ror E. MELVIN, citizens of the United States, all residing at Chicago, in the county of4 Cook and State of Illinois, have invented certain new and useful Improvements in Laundry lVringers, of which the following is a specification.

This invention relates to laundry wringers.

One of the objects of the invention is to simplify and cheapen the cost of construction of wringers.

A further object is to provide a wringer in which the parts may easily be assembled. A further object is the provision of simplified means for independently tensioning the rollers.-

Another object is the provision of effective and simplified means for releasing the spring tension on the rollers.

Another object is the provision of a frame in whichrelatively long compression springs are used to permit increase in the latitude of relative movement of the rollers and which springs are arranged for coincident adjustment and simultaneous release.

Another object is to provide a safety release whereby the tension efect of the springs may instantly be removed from the rollers by a very small movement of an accessible lever.

Another object is to provide a frame which completely encloses all of the working parts of the wringer except the working surfaces of the rollers.

Another object is generally to improve wringers.

Other objects and advantages will 'beloome yreadily apparent to persons skilled in the art from a consideration of the specification when taken in conjunction with the drawings, made a part hereof, and in which Fig. 1 is a side elevation of the wringer with one portion of the frame removed.

Fig. 2 is a section taken on line 2-2 of Fig. 1 when both members 'of the frame are in place. v Fig. 3 is a section taken Fig. 1.

on line 3 3 of Fig. 4 is an enlarged section taken on line 4- 4 of Fig. 1. y

Fig. 5 is an isometric perspective view of one of the bearing blocks in which the lower roller is journalled. 1

In allJ the views the same reference characters are used to indicate corresponding parts.

The framecomprise's two major members or parts A and B, the latter is hinged to the former at 10-10. The major portion A of l the frame may be connected to an angle bar support 11 by bolts 12. .Each frame member has two depending legs 13-13 and 111-14', respectively. The two parts A and B of the frame are held in` connected relation by .bolts 15.

- Each frame Amember including its legs are hollow and each membercarries'part of a gear housing 16-16, respectively, and this housing is extended on each member to include portions 17 to overlie one end of both rollers. Another similar roller housing 18 is a part of each frame memxber and .overlies the other ends of the rollers. These housings 17--18 prevent access to the ends of the rollers and serve as guards to prevent fabric from winding around the shafts upon which the rollers are mounted.

Roller 19 is journaled in bearing blocks 20-20 and is relatively fixed in posi ion. l

The journal 21 upon which the roller 19 is mounted carries onone end a clutch member 22 for driving connection with the clutch member 23. VThe other end of the shaft 21 projects'into the gear casin s 16-16 and carries atoothed pinion 24 or meshing relation with toothed pinion 25 which is also in the gear casing and which is'secured to the shaft 26 upon which 'the roller 27 is mounted. The shaft 26 is journaled .in rectangular bearingA blocks 28-28 at its respective ends and these are within the walls of the frame. The downward movement of the bearing blocks 28-28 is limited only by contact of the rollers 19 and 27, one with the other.

The blocks 28-28 are guided within the ends of the frame members by side walls 29-29 and by the stili'ening ribs 30 and end I walls 31. The ribs 30 extendxto thelishaft 26 on each side, so that the shaft and its roller may freely be moved vertically Awith its 1l1 earing blocks enclosed within the guide wa s.

A chamber 32 is jointly provided in the frame members above the rollers 19-27. In this chamber a floating bar 33 is located. It has perforated, bifurcated endsrhaving members 34-34 at each end. Pvoted between the members 34-34, as at 35, is a lever 36-36 having a down-turned end 37 which rests, at each end of the bar, upon the top of the journal blocks 28-28, respectively. The levers 36-36 each have an upturned end 38, pivoted to a spring guiding block 39, at 40. The blocks 39 engage the outer ends of the open compression springs 41-41, respectively. The innerl ends of thefsprings bear against abutments 42-42, which risefrom the bar 33 and' whichare, preferably, integral parts thereof.

When the bar 33 is depressed the up.

standing members 38 of the levers 36-36 are moved inwardly, whereupon the springs 41-41 are thereby compressed and the rollers 27 and 19 are more intimately brought into contact.

A block 43 extends outwardly thru the walls 31--31 of the frame members, carries a plate 44 which can not pass thru the openings in the walls 31-31, and is formed at its lower end into two oppositely disposed tapered and curved lcams 45 and 46, the higher part and the lower part of each cam terminates in a slot 47.

An internally threaded tube- 48 lpasses thru the part 43 and is provided with a cross bar 49 secured to its upper end by which to rotate the tube. Secured to the tube, or integral parts thereof, are lugs'v 50-50 whichN ride upon the cams 45 and 46,

respectively, and 'which enter the slots 47 as the tube is rotated by the cross bar.

Threaded into the tube 48 is a stem 51, provided with a hand wheel 52 xed to its upper end. the lower end of which passes lthru a stirrup 53 fixed to the bar 33 to hold the latter in place. By means of .the threaded stem 51 the bar 33 may be depressed to tension the springs 41-41L The springs when stressed tend to lift the bar 33 by the end 37 of the lever 36 acting as a fulcrum and yieldinglyy holding the bearing blocks 28-28 and the roller 27 depressed when the bar cannot be raised, therefore the further the bar -is depressed by the threaded stem 51, the greater will the springs 41-41 be tensioned and the rollers are thereby more firmly held together. This tension on the rollers may quickly be released by rotating the cross bar 49 until the lugs 50-50 drop off the cams 45-46 into the slots 47, wherey upon the bar 33 will be released and will be moved upwardly by the springs, and thus 4 gether has now been removed. l

The cross bar 49 serves as a safety means 70 to quickly remove the stress of the springs upon the rollers and, furthermore, it is a convenient means for this purpose supplemental to the operation of the threaded stem 51. The desired tension of the springs may by the bolts 15. The frame members may be punched and formed of sheet metal or they may be made in form of castings.

A drip board 53 is placed over` pins 54, which support it, and on its under face it has hooks 55 which limit its movement be- 90 low the rollers, and permit it to assume an vinclined position on either side of the rollers when it is shifted. Having described our invention, what we claim as new and desire to secure by Letters Patent, is z- 1.
